Quick change over tooling for a welder

Abstract

A weld stack includes a horn having a weld end, a polar mount adapted to receive a portion of the horn therein, a first adjustment ring coupled to the polar mount at a pre-determined distance from the weld end of the horn, and a second adjustment ring coupled to the polar mount adjacent the first adjustment ring, wherein the second adjustment ring includes a fine adjustment device for adjusting a relative position of the first adjustment ring and the second adjustment ring.

1. A weld stack comprising:
 a horn having a weld end; 
 a polar mount adapted to receive a portion of the horn therein; 
 a first adjustment ring coupled to the polar mount at a pre-determined distance from the weld end of the horn; an alignment pin protruding from a surface of the first adjustment ring; and 
 a second adjustment ring coupled to the polar mount adjacent the first adjustment ring, wherein the second adjustment ring includes a fine adjustment device positioned to engage the alignment pin for adjusting a relative position of the first adjustment ring and the second adjustment ring. 
 
     
     
       2. The weld stack according to  claim 1 , further comprising a locator coupled to the polar mount, wherein the locator includes a rounded end to engage the horn. 
     
     
       3. The weld stack according to  claim 1 , wherein the horn includes a datum structure to cooperate with a locator. 
     
     
       4. The weld stack according to  claim 1 , wherein at least one of the first adjustment ring and the second adjustment ring is a split collar. 
     
     
       5. The weld stack according to  claim 1 , wherein at least one of the first adjustment ring and the second adjustment ring includes a quick coupler for adjusting an interior diameter thereof. 
     
     
       6. The weld stack according to  claim 1 , wherein the first adjustment ring includes a channel formed thereon to receive a pin for aligning the weld stack. 
     
     
       7. The weld stack according to  claim 6 , wherein the first adjustment ring includes a flexible tab disposed in the channel to adjust a dimension of the channel. 
     
     
       8. The weld stack according to  claim 1 , wherein the fine adjustment device is a micrometer disposed for exerting a force on the alignment pin to adjust a relative position of the first adjustment ring and the second adjustment ring. 
     
     
       9. The weld stack according to  claim 1 , wherein the horn is in communication with an accelerator and at least a portion of the accelerator is received by the polar mount.
